"Currently the PHPIDS detects all sorts of XSS, SQL Injection, header
injection, directory traversal, RFE/LFI, DoS and LDAP attacks. Through
special conversion algorithms the PHPIDS is even able to detect
heavily obfuscated attacks - this covers several charsets, entities of
all forms, comment obfuscation, obfuscation through concatenation,
shell code and many other variants."
